WALKING EDGER Cyrus Sanford, Venice, Calif. ApplicationDecember 16, 1944; Serial No. 568,495 1 Claim- (01.94-45).

The device of this invention refers to edgers, a form of trowel, used to finish cement work, and more particularly cement sidewalks and similar surfaces. Ordinarily such finishing work is completed by the use of a tool which requires that the worker operate in a bent position and frequently such work in the past could only be accomplished by the worker when in a kneeling position, thus not only making the work tiresome in the extreme, but also slow and expensive.

The prime object of the present invention is to provide a cement finishing tool which is relatively easy to operate and whichenables a cement finisher to do his work while in standing or slightly stooped position in contrast with the conditions of physical discomfort which have heretofore prevailed as above set forth.

A further object of the invention is to provide a walking edger which is reversible in nature whereby the same surface can be repeatedly worked without removing the surfacing tool from contact with the semi-fluid surface being worked.

A still further object of the invention is to provide a simple, low cost, and efficient cement surfacing tool.

A still further object of the invention is to provide a convenient and practical means whereby any cement finishing tool can be converted to use when in standing position.

Other objects, features, and advantages of the invention may be apparent from the accompanying drawing, the specification, and the subjoined claim.

In the drawing, of which are two sheets:

Figure 1 is a side-elevational view showing the improvement which constitutes the instant invention attached to an edger for cement finishing, and in which the ferrule is broken away.

Figure 2 is a perspective view showing the device of this invention in functional position upon a cement surface shown as a fragment thereof, and in which the handle is shown broken away.

Figure 3 is a view of a modified form of the invention wherein the device is shown having a plural number of teeth or notches for adjustably positioning the handle to a lower than normal position for working relatively large expanses of cement in those cases where it is impractical to work from all of the sides of the job, in this figure the ferrule of the handle is broken away to show only a portion thereof.

The device of this invention is a walking edger and is indicated by the reference character H], which is shown as comprising a standard edger 12 upon which I secure as by riveting, an angle iron l4- having a plural number of notches' l6- formed in the upper edge thereof. In the form of the invention shown in Figures 1 and 2, I show one notch in the angel iron upon each side of the handle, while in Figure 3 I show a plural number of such notches upon each side of the mid-vertical center of the fulcrum or rather the pivot point of the handle, and the purpose this variance'of construction will be hereinafter set forth.

The vertical leg 18 of the angle iron I4 is provided with an opening or hole 20 through which I insert a bolt 22 preferably provided with a wing-nut 24, and which bolt also extends through the sides 26 of a yoke l9 which terminates in a ferrule 28 adapted to receive a handle 30 for manual application of the tool Ill.

As shown in particular in Figure l, I place a small flat piece of metal 32, and having the angular faces 34 and 36, in the space defined by the sides 26 of the yoke l9 and so secured thereto as by welding, that when the handle 30 is inclined in one direction or the other, that the handle and the assembly directly associated therewith is supported in an angular position by one of the angular faces 34 and 36, and the prime purpose of this arrangement is to form an abutment to transmit pressure to the edger blade when necessary without relying upon the pivot point formed by the bolt 22 to carry such pressure.

At a point in medial longitudinal alignment with and spaced from the bolt 22 I hingedly secure pawls 40 and '42 which as shown in the drawing are formed of angle clips having one of the faces thereof cut-away to enable the clips or pawls to be placed in contact and to be held in hinged relationship by means of the rivet 44 or other suitable means. A spring 46 attached to the faces or legs 48 and 50 of the clips or pawls constantly pulls them toward the longitudinal axis of the handle 30 and thus holds the pawl 40 and 42 in its associated notch l6 (see Figure 2) while the pawl 52 is in pressure contact with the top or upper edge of the angle iron I 4 and will automatically fall into the notch l6" after the pawl 40 has been lifted from the notch l6 and the angular position of the handle 30 has been swung in an opposite direction, such as indicated by the arrow A. The tool may be reversely used, that is the handle 30 may be inclined in either the direction indicated by the arrow A or B and it will function with equal facility and when thus reversed the pawls will function to aid in carrying the thrust of pressure as applied to the handle 30 and in cooperation with the faces 34 .and 36 will carry or transmit the downward and forward pressure applied to the handle when working a cement surface.

The present invention which resides in the means devised to reverse the handle of an edger, may be applied to any type of cement finishing tool such as toe edgers and other types of special cement finishing or surface working tools. The invention may in fact be made and sold as a kit to be applied and/or attached to other forms of manually worked tools in or to which it is desirable to apply or attach a means to reversely operate the same, and it is this feature which forms the essence of the invention.

Iclaim: v

In a cement finishing tool, a surfacing blade having an angle iron fixedly secured thereto, said angle iron being formed with a plural number of notches in the free edge thereof, a yoke pivotally secured to said angle iron and a handle for said yoke whereby said tool may be function- REFERENCES CITED The following references are of record in the file of this patent:
